Orchid pseudobulbs are false bulbs that serve the plant to store moisture and minerals. These bulbs can be green, cylindrical, spherical or flat.

The length of the pseudobulb depends on the light under which the plant is grown. Pseudobulbs can have 2-3 leaves at the very top and from one to several pairs of leaves along their surface. The lifespan of one false bulb is 2 to 3 years.

What it is?

Bulba is an underground bulb. It looks like potato tubers.

And, just like the pseudobulb, it has the ability to retain moisture and nutrients.

But there are some differences between the bulb and the pseudobulb:

  1. Location. The pseudobulb is located above the ground.
  2. Diameter. Its diameter can be much larger than that of a bulb.
  3. Color. The aerial bulb has a bright green tint.
  4. Pseudobulbs, as a rule, have 1-2 leaves at the crown and several pairs of leaves arranged horizontally towards the false bulb.

After the orchid completes its flowering, it is not recommended to cut the pseudobulb. It continues to serve the plant as a food source for young shoots during the period of their active growth. As a rule, you need to wait for the bulb to dry on its own. In these types of orchids that bloom at home, the bulb is absent, and the leaves play a water-retaining role.

An orchid that blooms with brightly colored flowers, the pseudobulb has a bright red hue.

Where is the false bulb located?

The formation of a pseudobulb in an orchid begins on the stem in thickened internodes... And the false bulb is located, right on the aerial part of the plant.

Orchids are divided into two types: monopodial and sympodial. The first type of this plant does not have bulbs. But as for sympodial plant species, they have pseudobulbs. Such orchids have numerous side vertical stems. And, as a rule, they "can afford" to release special storage organs from the shoots. These include:

  • imbidium;
  • dendrobium;
  • encyclia;
  • miltonia;
  • epidendrum;
  • odontoglossum;
  • cattleya;
  • lelia;
  • cellogines and many others.

These types of orchids grow in a horizontal direction, and pseudobulbs are formed on their aerial parts.

It is worth noting that sympodial orchids, like other species, have a certain dormant period, without observing it, many species will simply not bloom.

Sympodial orchid species have multiple growth pointsdeveloping from new shoots. And each of these sprouts, after a while, turns into pseudobulbs.

The following are various photos of a flower with a false bulb, also with thin roots and narrow leaves:

The role of the false bulb

Bulba plays a very important role in the life of the orchid. It is able to prevent the evaporation of moisture, which is necessary for the plant to fully develop. Pseudobulb allows the plant to survive in adverse and extreme weather conditionsespecially during long dry periods.

Bulba also participates in the process of flower photosynthesis, converting carbon dioxide into oxygen. If the orchid is provided with timely and proper care, then the functions of the pseudobulb will decrease.

The presence of a bulb indicates that the plant is adapted to development, both in dry conditions and with high humidity.

How to care for an aerial tuber?

The bulb has been found to retain moisture for the plant. This means that these types of orchids can develop for a long period of time without watering. This period of time in an orchid is called a dormant period. This phenomenon was due to severe droughts in their homeland. At the time of which, the plants developed at the expense of previously accumulated resources.

Therefore, first of all, it is necessary to provide full care for the orchid bulb. This requires:

  • Observe the temperature conditions in the room. Bulbs prefer colder temperatures.
  • Full lighting. Pseudobulbs, like the plant itself, love bright light.
  • Watering. Watering is necessary only when the pseudobulb begins to wrinkle. With regular watering, I will break the dormancy and the plant will die.
  • Fertilizer. This should be done once every 3-4 weeks. Fertilize the bulb and the substrate with special mineral dressings.

Do not water too often. This type of plant tolerates drought better than waterlogging.

As it turns out that pseudobulbs are not available for every type of orchid... And only those that are grown in natural conditions. The plant needs them in order to prevent moisture evaporation and participate in the photosynthesis of the flower. But observing all the rules for caring for an orchid, pseudobulbs reduce their functions.

For the full development of the plant, it is necessary to provide bright lighting and proper watering. But it should be noted that for this type of plant it is better related to drought than to strong moisture.
